Put sockets in the pads, then go ahead and try whatever you have!
And remember to use plier to bend the leads, not fingers. I also cracked a 1n34 lately by nudging it around too hard.
I just finished a SWAH, myself. Didn’t try the D9B I have sitting around (remember, soviet diodes are marked backwards), but that Vf is in line with the upper end of 1n34 I’ve seen.
I ended up using a bat42, which is at the lower end of the 1n34 range. Mine read at .324V. Working pretty well. Test a couple bat41s, I’m betting those would work and ones on the lower end of the variance would overlap with 1n34 range.
